These three codes have to do with your exhaust gas temperature sensor 2 circuit in engine bank 2. The precise code you experience has to do with the specific problem that you’re experiencing:
- P2034: Exhaust Gas Temperature Sensor Circuit – Bank 2, Sensor 2
- P2035: Exhaust Gas Temperature Sensor Circuit Low – Bank 2, Sensor 2
- P2036: Exhaust Gas Temperature Sensor Circuit High – Bank 2, Sensor 2
As you can see, the first code is just a general warning code indicating that something is wrong with the circuit, the second code indicates that the circuit is low, and the third indicates that the circuit is high. While still generic codes, these different codes can give you more insight into what’s actually happening in your vehicle.
More About the P2034, P2035, and P2036 Codes
The exhaust gas temperature sensor monitors the temperature of the gas coming out of the exhaust. This is important because very high exhaust temperatures can result in the failure of the engine or the turbocharger, and if the temperature is very high, the engine needs to be able to readjust and change the temperature. However, if there’s a problem with the exhaust gas temperature sensor, it won’t be able to do this, which is what sets this code. Additionally, it will generally trigger a Limp Home mode or Reduced Fuel mode to prevent engine damage, which can negatively impact your vehicle’s function.
What Are the Symptoms of a P2034 Code?
Generally, the P2034, P2035, and P2036 codes don’t actually have a lot of serious symptoms. You should notice that the check engine light will turn on, but outside of that, there may not be a lot of other symptoms. However, if this is a code being accompanied by other codes, you might notice symptoms for those codes, which is one of the reasons it’s so important to pay attention to the actual codes your engine is throwing.
What Are Some Causes of a P2034 Code?
There are a number of different potential causes of the P2034, P2035, and P2036 codes. An exhaust leak may cause this problem, as well as any problems with the electrical connections directly to the sensor or in the circuit surrounding the sensor. In some cases, it may just be that the bank 2 sensor 2 exhaust gas temperature sensor has completely failed, although you should only consider this as an option if you’ve already looked through the other possible causes.
How Serious Is the P2034 Code?
At first, the P2034, P2035, and P2036 codes will not be exceptionally serious. Most of the time, you won’t even see any driveability concerns with these codes. However, over time, it can lead to more serious concerns. After all, the P2034, P2035, and P2036 codes can cause your engine to be unable to read the exhaust gas temperature, especially if you’re also experiencing issues with other sensors and banks, and if the engine allows for a very high temperature over a long period of time, you’re likely to experience more serious issues. Get this problem fixed as soon as possible to avoid future concerns.
Can I Still Drive with a P2034 Code?
While you can physically drive with the P2034, P2035, and P2036 codes, it’s best to avoid doing so if you know that these codes are active. The important thing to remember is that you shouldn’t be overly concerned if you notice these codes and you’ve been driving with the check engine light active, but you shouldn’t keep driving after you’ve discovered these codes active.
How Easy Is It to Diagnose a P2034 Code?
The diagnostic process for the P2034, P2035, and P2036 codes can be fairly difficult because there are many different possible reasons for them to be active. Whether the issue is with an exhaust leak, electrical connections, or the sensor itself, you’ll likely need some specialty tools and some general knowledge of your vehicle’s make and model to determine what the code problem is – things that an expert will have, but you may not.
How Difficult Is It to Inspect a P2034 Code?
Most people are not well-versed in the inspection process for the P2034, P2035, and P2036 codes. To inspect these codes appropriately, you need to know what it looks like when your vehicle is functioning normally, something that not everyone has. If you’re experiencing these issues, then most experts will recommend turning to professional help instead of trying to handle it on your own.
Need Additional Help with Your P2034 Code?
It’s common to need professional assistance when you’re dealing with these three codes, and no matter which one you see problems with, you should talk to an expert if you decide that you want some help with these codes.
The first step is to find a repair shop in your area with KBB. This service locator is a great starting point for anyone who’s trying to find a local professional to help with various vehicle problems.
Additionally, because this code is very generic, you might see other codes alongside it. Check out the KBB OBD-II database to learn more about those other codes as well.
